Definitions
- the invention relates to an inorganic-organic colorant composition of barium sulfate and CI. Pigment Red 170, as well as their use for coloring powder coatings.
- the production of powder coatings is known and consists essentially of three process steps as described in Park und Lack, 1986, 92, 734-737.
- the components of the powder coating such as Binders, hardeners, colorants and fillers and, if appropriate, auxiliaries and additives such as, for example, surfactants, pigmentary and non-pigmentary dispersants, setting agents, resins, waxes, defoamers, anti-dusting agents, extenders, preservatives, additives for controlling the rheology, wetting agents, antioxidants, UV absorbers, Light stabilizers, antistatic agents, degassing agents, lubricants or a combination thereof, weighed according to the powder coating recipe, dosed into a pre-mixer and mixed thoroughly.
- auxiliaries and additives such as, for example, surfactants, pigmentary and non-pigmentary dispersants, setting agents, resins, waxes, defoamers, anti-dusting agents, extenders, preservatives, additives for controlling the
- the premix is fed continuously to an extruder, melted, homogenized and the solid components dispersed by shear.
- the melt is rapidly cooled after it has left the extruder in order to stop or avoid the reaction between binder and hardener.
- the extrudate is then ground to the desired particle size distribution of the powder coating.
- Another disadvantage is the increased wear of the premixer and the extruder due to higher mechanical stress due to such inhomogeneities and Agglomerations. There is also a major disadvantage in the partial loss of the raw materials used. Another disadvantage is the increased cleaning effort.
- Powder coating partially used for the second process step, i.e. melting, homogenizing and dispersing in the extruder, modified processes.
- Some processes are characterized by a modification of both process steps in order to optimize powder coating production.
- DE-A-4 101 048 describes a modified process for producing a powder coating in which the binder and hardener components are premixed, fed continuously to the extruder and melted in the extruder. Pigments, fillers and other constituents are premixed separately and metered into the extruder at the end of the melting zone or in the subsequent homogenization or dispersion zone.
- a disadvantage of the manufacturer of powder coatings in this process is that a second premixer is required and, as it were, a further process step is implemented, which causes costs due to additional space, time and investment requirements.
- Another disadvantage of the cited method is that inhomogeneities and caking can also occur when the pigment, fillers and optionally further constituents are premixed separately.
- WO 91/13931 describes a process for the production of pigment concentrates (masters) and their suitability for coloring powder coatings.
- the master is produced from a mixture of colorant (s), fillers, wetting agent (s), polymer carrier (s) and possibly other additives (s) in an "adiabatic" high-speed mixer, the mass being melted by the frictional heat generated, is homogenized and dispersed.
- Such masters can be used as colorants for the production of powder coatings, an improved homogeneity of the powder coating, a higher color strength and an improved flow and gloss being observed than in the conventional incorporation of the colorant.
- the disadvantage here is that an additional process step, namely the production of the master in an additional unit, a special high-speed mixer, is necessary. This has an adverse effect on the time required and the cost of producing powder coating.
- a further disadvantage is that such a colorant preparation contains a large number of additives, the influence of which on the coating systems of the powder coating manufacturer cannot be predicted.
- Inorganic-organic colorant compositions are known, for example, from EP 0 702055, EP 0 702 063 and EP 0845 504.
- the pigment preparations described there with natural and synthetic silicates as inorganic filler are referred to as "stir-in" pigments, but do not meet the requirements already described with regard to Premix when incorporated into powder coating systems.
- Mica, kaolin and talc are mentioned as examples of natural and synthetic silicates.
- Pigment Red 170 (CI. 12475) is one of the most important colorants for pigmenting powder coatings in the neutral red range. In addition to its good heat resistance, it is characterized above all by excellent efflorescence in powder coating systems. Because of their tendency to bloom, e.g. the more yellowish pigment red 112 (CI. 12370) is only partially suitable and pigment red 3 (CI. 12120) is not suitable for this application. Other pigments, which are also similar in color to Pigment Red 170, are not suitable for replacing this pigment in powder coating systems without restrictions because of other important application properties, such as poor fastness in outdoor use, poor opacity or insufficient color strength.
- pigment red 170 in particular, has a high degree of inhomogeneity and caking when it is incorporated into powder coating systems, particularly during the production of the premix.
- the present invention is therefore based on the object of providing a material which essentially contains pigment red 170 and which can be incorporated into powder coating systems by simple mixing in a premixer without causing inhomogeneities and caking. Another object of the invention is to provide this material as inexpensively as possible, i.e. without additional

- the pigment preparations according to the invention are distinguished by excellent coloristic and rheological properties, in particular by an excellent rheology, high transparency and brightness and easy dispersibility. They are particularly suitable for use in powder coatings, but also as colorants for non-contact printing processes, e.g. in electrophotographic toners and ink-jet inks.

- colorants e.g. add white, colored or black pigments as well as effect pigments to the powder coating mixture.
- Epoxy resins optionally carboxyl- and / or hydroxyl-containing polyester resins, polyurethane and acrylic resins are typically used together with the usual hardeners as binders for powder coatings.
